基于不同经济状态的预期行为研究

经济行为人在做预期时会面临私人信息与公共信息。作为微观的经济行为人在面对不同经济状态时,对二者的均衡需求量是不同的。同时经济状态对二者的影响具有不对称性。在不考虑经济波动时,二者都具有正外部性,考虑经济波动时,公共信息具有负外部性。因此,预期行为随着经济状态变化而改变。

A Study of the Expectation Behaviour in Different Economic Situations

Economic actors have to deal with both public and private information when they make expectations.From a micro perspective,equilibrium quantity demanded of public and private information varies in different economic situations.At the same time economic situations exert asymmetrical influence on the two kinds of information.Both public information and private information have positive externalities if economic fluctuation is not considered,but public information has negative externalities if economic fluctuation is considered.Therefore,expectation behaviour varies according to economic fluctuations.
